Llke characters of reference designate corresponding parts throughoutthe several The improved harvester and thresher which forms the subjectmatter of this application comprises a main frame 20 supported uponwheels 21 and 22, the wheel 21 particularly at Figs. 1, 3, -4 and 5,such auxiliary frame carrying at its forward side a cutter bar ofsubstantially the usual and ordinary type indicated at 29, shown moreespecially atFigs. 4 and 5.

, The auxiliary frame 28 is hinged to the main frame 20-by means of ashaft 30 which extends entirely through the frame as indicated moreparticularly at Figs. 4 and 15. The shaft 30 isnot rotatable but rigidlymounted and rotating thereon are rollers 31 which carry aprons 32,rollers 33 being also provided adjacent the cutter bar 29 for carryingsaid aprons.

Mounted also upon the frame 20 is a' prime mover 34, here shown as aconventional internal combustion engine connected by means of a shaft 35and gear 36 with a line shaft 37 which also extends longitudinally 'ofthe machine as shown more particularly at Figs. 4 and-15; The shaft37 isprovided with a gear 38 intergeared with the gear 36 whereby such shaft37 receives motion from the prime mover 34.

The shaft 37 is provided with a chain and sprocket gearing, as shownmore particularly at Figs. 4 and 15, whereby connection is made with asleeve 30 carrying agear 40 intergeared with a gear 41 and rotating ashaft 42 to which issecured the pitman 43 which through the medium ofthe pitman 51 with sprocket chains 52 passing over such sprockets andthe sprockets 48 as shown more particularly at F igs.7 and 15. The

cylinders also comprise opposite cylinder heads having'hubs 53 andcentral hubs and supporting disks 54, as shown more particularly at Fig.6, all Of'SZIld heads and' supports being provided with arms 55 to whichthe cylinder bars 56 are rigidly secured by the use of the cylinderteeth 57 in i the usual well known manner whereby the cylinderstructure, as shown at'Fig. 6, be comesunusually rigid, the arms 55being preferably formed integral'with the heads and supports. Theseveralhubs 46, 53 and 54 areheld against longitudinal displacement upon theshaft 45 by the collars 45 abutting against the ends of said hubs, as

. integer shown especially at liig. 6 and provided with ground whichwould otherwise tend to throw the teeth 57 out of proper operativerelation with the teeth of the concave. 1n conjunction with thethreshing cylinders the usual concaves 58 are provided and are inclosed'by a housing 59 shown particularly at Figs. 5, 6 and 7 whereby grainpassing from the aprons 32 is received into the cylinder and isdischarged after being threshed upon the rattler rake 60. The rattlerrake 60-is con structed in substantially the usual manner of end beltsand slats but is also provided with intermediate wires 62 which preventthe straw from falling through between the slats of the rattler butoffer no obstruction to the passage of the grain therethrough.Beneath'the rattler rake 60 an inclined deck 63 is provided terminatingat its lower end in a trough 64 in which is rotatably mounted a wormconveyer 65. The worm conveyer 65 is driven by a sprocket chain 66from'the line shaft 37 and a beater 67 is provided at the rear edge oftherattler for forcing the straw downwardly at the rear of the machine.It will be noted that the beater 67 is driven by means of gear 68 fromthe rollers 69 which in turn receive motion from the line shaft 37through the medium of sprocket chain 70, as shown more particularly atFig. 15. The aprons 32 are likewise driven by sprockets and chains shownat 71 in Fig. 15 from the line shaft 37 connecting directly with therollers 31.

From'the conveyer worm 65 the threshed grain is discharged into a shoe72 from which it is raised by an elevator 7 3 and dis charged into ashoe 7% and again raised by an elevator '75 and discharged into a boot76 of the cleaner, shown as a whole at 77, the detail of such cleanerbeing shown particularly at Figs. 10 to 14 inclusive. The conveyer 73 isdriven from the worm shaft as indicated at 78in lFigJl and the conveyeris driven by a shaft 79 from the "cleaner drive hereinafter described.

The cleaner comprises a framework 80in the form of a housing as shownparticularly at Figs. 10 to 13 inclusive and is provided with a shakingframe 81 having a screen 82 upon which the grain is received from theboot 76. As disclosed particularly at Fig. 11 a second screen 83 isprovided underneath the first screen 82 and a shoe 8% also providedrigidly carried by the shaking frame 81 and moving therewith. Theshaking frame 81 is located at the top of the housing 80 and a secondshaking frame 85-is located at the bottom of the housing carrying likewise screens 86 and 87 and a shoe 88.

larly shown attached to the frame -connect1ng at its opposite ends withboth The shaking screen 81 is provided with a track member 89 bearingupon a roller 90 whereby longitudinal motion is permitted and theshaking frame 85 is provided with a similar track member 91 bearing upona roller 92 permitting similar movement of such shaking frame. Shakingof the frames 81 and 85 is accomplished by means of a bar 93 preferablythough not necessarily rigidly attached. to one of said frames asparticu- 81 and of said frames as shown at Fig. 13. The bar 93 isdriven'by means of a pitman 94 from an eccentric 95 carried upon a shaft96 pro vlded with a pulley 97 which receives motion through the mediumof a cross belt from a pulley 98 carried upon a shaft 99.

The shaft 99 receives motionthrough the medium of the gear 100 from themain drive 85 shaft 35 and serves to drive the cleaner. At their endsopposite the rollers 90 and 92 the shaking frames 8]. and 85 arerespectively provided with track members 101 and 10:2 bearing uponrollers 103 and 10 i respectively, such rollers being carried by a strutbar 105. The bar 105 is pivotally connected with a lever 106 which isprovided with a counterweight 107 adapted to equalize the weight of theshaking screens 81 and 85 and with a lateral offset 108 to which is suspended a pendulum weight 109 through the medium of which the screens ofthe shaking frames 81 and 85 are .continuously maintained in horizontalplanes.

At the outer end ofthe shoe 8% a fan casing-110 is provided in which ismounted a propeller fan 111 servingwhen rotated to produce a blast ofair in the shoe 8-1 under the screens 82 and-83. frame 85 a similar fanhousing 112 is lo cated in. which is mounted a similar fan 113discharging an air blast into the shoe 88 un der the screens 86 and 87.4

It will be noted especially from 'Figs. 10, 11 and 12 thatthe shoes 84and 88 are curved at the bottom, the curvature naturally increasing inradius toward the adjustable end of the shoe, and that the blast fromthe propeller fans'111 and 113 will, therefore be introduced into thesecurved shoes in a rotating condition. It has been found from exhaustiveexperiments that the introduc. tion of the blast into such a curved shoeby the use of a propeller fan introducing the At the lower shaking blastin a rotating or spiral condition serves I shaking frame 85.

a worm 115 is mounted to. rotate within such trough Lpon the shaft 116.The worm 115 receiving the grain from the shoe 84, moves such grain inthe direction indicated by the arrow in Fig. 11 over the 'carborundum orabrading surface and thereby serves to completely thresh and shell anykernels of grain which have reached this stage of the process whilestill carrying some of the chaff therewith. At the end of its movementthe grain is dropped through an opening 117 onto a worm 118 carried by ashaft 119 and operating in a trough composed of a screen 120. Theconstruction of the worm 118.is shown more particularly in detail atFig. 14 comprising a core or large shaft 121-nearly filling the screentrough 120 with a very narrow fin 122 about such core 121 so that butlittle space is provided between the core and the trough. The fins arefurther provided with webs 123 spaced at intervals whereby the grain isthrown by the conveyer upwardly and thus agitated to properly distributethe grain so conveyed through such screen 120 upon the screen 86 of the86 is provided a spout 124 shown atFigs. 11, 12 and 13 from which anyextraneous matter too large to pass through the screen 120 is finallydischarged. A discharge shoe 125 is also provided to receive grain fromthe shoe 88 from which it is carried by a conveyer 126 to the dischargespouts 127 for bagging, a platform 128, as shown more particularly atFigs. 1 and 2, being provided to carry an operative for handling thebags. It will be noted that the shoes 84 and 88 are provided withcorrugations 129 by which the grain upon such shoes is forced downwardlyeven against the blast of air from the fans 111 and 113.

To drive the various working parts of the cleaner 77 the shaft 99 isprovided with a sprocket 130 shown at Fig. 4, having a sprocket chain131 passing thereover extending to ,a double sprocket 132 seen at Fig. 2

from which passes a sprocket chain 133 to a double sprocket 136 carriedupon the shaft of the fan 113, seen at Fig. 11. Upon the shaft of thefan 111 a sprocket 134 is carried over which extends a sprocket chain135- to a sprocket carried upon the shaft 79 which actuates the conveyer75.

Carried also upon the shaft of the fan 113 is a sprocket 136 seen atFigs. 11 and 13 over which passes a sprocket chain 137 passing over asprocket 138 seen at Fig. ll'mounted upon the shaft of the fan 111 sothat said fans 111 and 113 are driven in unison.

To drive the worms 115 and 118 which should be driven slower than thefans 111. and 113 a small sprocket 139 is carried by the shaft of fan111 over which passes a sprocket chain 140 and also over an idler At theend of screen 141 which idler is carried upon a shaft 142 carrying inits turn a small sprocket 143. The sprocket 143 carries a chain 144passing in turn about the sprockets 145 and 146 carried upon the shafts116 and 119 respectively operating the worms 115 and 118. It will thusbe seen that all of the moving parts of the cleaner are actuated throughthe medium of the sprocket chain 131 from the countershaft 99.

The auxiliary frame 28 in addition to being supported upon the mainframe 20 by the shaft 30 is further supported by cables 147 which passover bearing pulleys 148 and are connected with the auxiliary frame 28at its forward edge adjacent the cutter bar as indicated at 149. Therearward ends of the cables 147 are connected to one arm 150 of abell-crank lever, the other arm 151 of which extends rearwardly adjacentthe tiller 26 and is provided with a manually operated detent 152engaging a rack bar 153 connected with the beam 23 so that bymanipulating the arm 151 of the bell-crank lever the auxiliary frame andits cutter bar and other carried parts are the shaft 156 of the reel.The pivoted arms 155 and the shaft 156 are maintainedadjustably inposition relative to the cutter bar by means of-braces 157, theadjustability being accomplished by utilizing the holes in said brace157.

' The reel shaft 156 receives motion by means of a sprocket 158-carriedby the grain wheel 22 over which passes a sprocket chain 159 operating asprocket 160 upon a. shaft 161 which in turn carries a sprocket 162 witha chain 163, the latter chain passing also over a sprocket 164 upon thereel shaft 156. It is necessary or highly desirable to drive the reelfrom one of the traction wheels so that the speed of rotation of thereel will at' all times correspond exactly. with the speed of themachine so as to properly hold the grain in engagement with the cutterbar and place the cut grain upon the aprons. As the aprons 32 as well asthe rattlers 60 are spaced apart at the center of the machine toaccommodate the gearing referred to, a divider 165 is employed as shownparticularly at Figs. 1, 2 and 4 and the reel is divided in the middleas at 166 shown at Figs. 2 and 4 particularly.

The reel is constructed for the most part with sets of usual ordinaryreel slats -0f the reel frame, as shown at 167, but in order to permitthe machine to cut the grain to the full width of the machine, Iprovide-an auxiliary reel extension com prising auxiliary pivoted reelarms 169, which carry pivoted slat sections 170. The

'2 and 9.

anteater end of the cutting table adjacent the reel extension isprovided with a housing 168, to cotiperate with the pivoted reel slatsections, which is of sufficient lateral eX- tent to cover the path ofthe traction wheel in the rear as indicated particularly at Fig. 1. Thesides of this housing 168, are inclined toward the apron as indicated inFi s. The auxiliary slat sections 110 are normally held in alinementwith the main slats 167 by springs 171, but as the slat sections passover the inclined sides of the housing 168, they are swung upon theirpivots in the manner. indicated in Fig. 9, and after passing the housingthey are returned to normal position by the springs 171, a clip 172being provided to limit the movement thereof.

guide 173 and'ride up the guide as indicated more particularly at Figs.8 and 9 whereby. the slat sections follow substantially the contour ofhousing 168. As shown in the drawings the slat sections carry brushfibers 175 which assist in properly It is to be understood, however,that the brush fiber 175 is not essential to the present invention andthat under ordinary conditions the slat sections 170 alone willaccomplish the purpose desired. i

As shown particularly at Figs. 2, 3 and 4 a clutch 176 is providedbetween the prime mover 34 and the drive shaft 35; one of the clutchmembers, as for instance that mounted upon the engine shaft, will beconsidered as movable. said movement being effected by a lever into andout of engagement with the other clutch member. It is to be understood,of course, that while a clutch of the kind mentioned has been shown anygearing of the usual and ordinary type is within the scope of that partof the present invention.

" To maintain the cleaner with its screens in transverse horizontalposition the cleaner is mounted in straps 177 rigidly secured to orintegral with a sleeve 178 see Fig. 16 carried upon a shaft 179 wh chsaid shaft is mounted as a bearing upon the main frame 20 permitting thestraps 177 and the sleeve 178 and the cleaner carried thereby to moveabout said shaft as an axis. The hull wheel 21 is also journaled uponthe sleeve 178 by means of a lateral sleeve 180 extending therefrom witha shaft 181 inserted through such lateral sleeve 180 as shown moreparticularly at Fig. 16. The shaft 181 forms the journal for the bullwheel 21 so that the axle of the bull wheel is rigid in relation andcleaner move angularly upon the shaft 179 as described,

turned serves to move the segment about its pivot upon the shaft 179. Toturn the worm 18,6, gears-187 and 188 are carried upon the shaft 99 witha clutch member 189between such gears, the clutch member being splinedto the shaft 99 in the usual well known manner and a lever 190 isprovided for moving the clutch member 189 longitudinally of the shaftinto engagement with the gears 187 and 188 respectively.

To actuate the lever 190 to throw it respectively into and out. ofengagement with the gears 187 and 188 a pendulum weight 191'is pivotedupon the platform 128 and is cor1- nected by means of links 192 and 193and a bell-crank lever 19 c with the lever 190 which is pivoted upon theshaft 195 so that as the pendulum weight 191 swings under the tilting ofthe machine the clutch member 189 is thrown into and out of engagementwith the gears 187 and 188to rotate the worm 186 in either requireddirection to move the bullwheel, cleaner and associated parts angularlyupon the shaft 179. A handle member 196 is also provided whereby theoperative standing upon the bagging platform-128 may manually cause theplatform to tilt or right itself as occasion may make desirable.-

The bracket 185 is provided with arms 197 which extend upon oppositesides of the segment 183 and a block 198 is inserted through the slot181 of the segment and pivoted by means of a bolt 199 so that thesegment is held at all times slidably in engagement with the worm186.

The shaking screens 82 and 86 are mounted as above stated upon frames'81and 85. The construction of these screens 82 and 86 is similar and atFigs. 17, 18 and 19 such construction is shown, the numbers referring tothe screen 82 but it is to be underfrom the main frame for access to thecylin ders or for other purposes. The separability of the hinge isaccomplished by means of a strip 201 secured to the auxiliary frame 28at required intervals and through such strip the shaft 30 extends. Astrip 201 is hinged upon the rod 30 in contact with .the strip 201 and astrip 202 is secured to the main frame 20 at each interval correspondingto the strips 201 and is provided with a slot 203 proportioned toreceive the shaft 30 when the auxiliary frame is moved into engagement.The strip 201 is provided with holes 204 proportioned to register withsimilar holes 205 in the strip 202 when the members are moved together,as shown at Fig. 20 and through such registering holes bolts 206 areinserted. The removal of the bolts 206 permits the separation of thehinge members without disturbing the various rollers, sleeves, bearingsand other members located and rotating upon the shaft 30 as beforedescribed, the complete separation being permitted by the disconnectionor removal of the sprocket chains 39 and 71.

As the auxiliary frame is supported from the main frame by means of suchhinge joints and the cable 47 whenthe hinge is separated it becomesdesirable to provide means for supporting the auxiliary frame 28 insubstantially the right height for again coupling with the main frame.For this purpose legs 207 are hinged to the under side of the auxiliaryframe at such intervalsas may be found necessary or desirable and areheld ordinarily in inoperative position by a keeper 208. It is obviousthat when the legs 207 are swung down to operative position they willengage the ground and the auxiliary frame may be disconnected from themain frame and still supported upon the legs 207 in proper position foragain coupling with the main frame 20 when the trouble has been removedand it is desirable to couple the frames together.

In operation, as will be apparent from the foregoing description, themachine is pushed rather than pulled by the draft animals attached atthe evener 27 but no part of the mechanical structure is driven by thepropulsion-of the machine except the reel. The other structure is alldriven from the prime mover 34 through the medium of the main driveshaft 35 and in the manner described for the various parts of themachine, such operatmn belng. described 111 c'On unctmn with thedescription of the parts themselves. It will be apparent that the graindeposited upon the aprons 82 by the reel :will be conducted directlyinto the threshing cylinder, "from. which cylinder the threshed grainand straw will be deposited by the momentum imparted thereto by thecylinder upon-the rattler 60. The threshed grain, chaff and smallparticles will fall through the rattler onto the deck.63 and into andupon the conveyer 65 which "transfers such threshed grain to theconveyers 73 and 75 bywhich it is elevated into the cleaner 77. Theaction of the grain in the cleaner has been thoroughly and completelydescribed inconnection with the description of the cleaner itself andwhen the cleaning is completed the cleaned grain is discharged intoposition to be operated upon by the bagging conveyer 126 by which it isdischarged through the bagging spouts 127 and bag as shown at Fig. 2.

pecial stress is laid upon the construction I v and operation of thethreshing cylinders operating as they do upon a fixed shaft with collarsto prevent the end thrust of such cylinders. It is obvious that inconstructing the cylinder and journaling it as shown, the entire bearingin the hub of the cylinders is subject equally to wear. and that if anypart of the shaft 45 is subjected to greater wear than any other partthe.

shaft may be turned to compensate for such wear so that the cylinderbecomes by reason of its mounting capable of a longer operative lifethan" as though mounted'upon a shaft which shaft-was journaled torotate. Also by fixing the shaft rigidly and mounting the cylinders uponthe same as shown all end motion is avoided and the' teeth of thecylinder are properly spaced relative to the teeth of the concavethereby preventing the crushing and grinding of the grain as it passesthrough.

Special stress is also laid upon the hinging the bearing for the rollerscarrying the aprons as well as carrying the drive for the cutter bar. Bythis means the same wear in relation to the mounting of the cylinder andin addition thereto the aprons 32 always remain at the desired tensionirrespective of the tilting of the auxiliary frame and the cutter barmechanism receiving motion from a gear atthe center of tilting of theplatform also at all times remains in proper tension, v

Special stress is also laid upon the cleaner and especially on thosefeatures of the cleaner comprising the blast structure and the levelingof the shaking frames. The use of the screw conveyer with the abradingtrough and of the lower conveyer with 11o ing of the auxiliary 'frame28-to the 11121111 frame, it being hinged upon a shaft form- 11 5resistance is accomplished as just described neat the agitating Webs anddistributing screen is also particularly emphasized.

Another point particularly emphasized in regard to the structure is thefact that the draft horses with the exception of one horse at most havea practically clear View ahead. It has been found by experience thatwith an obstructed View ahead, draft horses many I DlIlCllinorewillingness isfound on the part of the horses to perform theirlabor.

Special stress is also laid upon the con struction'of the reel with thehinged section whereby thegrain Wheel travels Wholly in the clear and'does not trample down the standing grain.
